GHz Circuits, Inc. was established in 2005 to address the challenges in designing mixed-signal circuits running at multi GHz speeds in deep nanometer CMOS. The company is headquartered in Silicon Valley and has an international roster of clients.
GHzC has developed over time to specialize in the field of providing high fidelity clocking solutions to enable customer’s SoC products in the fields of communications, computing, consumer and enterprise segments.
GHz Circuit’s solutions are two pronged :-

EDA tools to accurately simulate PLLs in transient domain by using proprietary behavioral modeling techniques. This results in a speed up of 104-105 as compared to conventional circuit simulators

Design and license of high fidelity clocking circuits IP in the latest deep nanometer nodes
